IBM PC 5150
===========
- Intel 8088 at 4.77 MHz derived from a 14.31818 MHz crystal
- Onboard RAM: Revision A mainboard - min. 16KB, max. 64KB
Revision B mainboard - min. 64KB, max. 256KB
- Total RAM (using 5161 expansion chassis or ISA memory board): 512KB (rev 1 or rev 2 bios) or 640KB (rev 3 bios)
- Graphics: MDA, CGA, or MDA and CGA
- Cassette port
- Five ISA expansion slots (short type)
- PC/XT keyboard 83-key 'IBM Model F' (some early 'IBM Model M' keyboards can produce scancodes compatible with this as well, but it was an undocumented feature unsupported by IBM)
- Optional 8087 co-processor
- Optional up to 4 (2 internal, 2 external) 160KB single-sided or 360KB double-sided 5 1/4" floppy drives
- Optional 10MB hard disk (using 5161 expansion chassis)
- Optional Game port joystick ISA card (two analog joysticks with 2 buttons each)
- Optional Parallel port ISA card, Unidirectional (upgradable to bidirectional (as is on the ps/2) with some minor hacking; IBM had all the circuitry there but it wasn't hooked up properly)
- Optional Serial port ISA card

=========
IBM PC-XT 5160
==============
- Intel 8088 at 4.77 MHz derived from a 14.31818 MHz crystal
- Onboard RAM: Revision A mainboard (P/N 6181655) - min. 64KB, max. 256KB (4x 64KB banks of 9 IMS2600 64kx1 drams plus parity); could be upgraded to 640KB with a hack; may support the weird 256k stacked-chip dram the AT rev 1 uses)
Revision B mainboard - min. 256KB, max 640KB (2x 256KB, 2x 64KB banks)
- Total RAM (using 5161 expansion chassis, ISA memory board, or rev B mainboard): 640KB
- Graphics: MDA, CGA, MDA and CGA, EGA, EGA and MDA, or EGA and CGA
- One internal 360KB double-sided 5 1/4" floppy drive
- PC/XT keyboard 83-key 'IBM Model F' (BIOS revisions 1 and 2) (some early 'IBM Model M' keyboards can produce scancodes compatible with this as well, but it was an undocumented feature unsupported by IBM)
- 84-key 'AT/Enhanced' keyboard or 101-key 'IBM Model M' (BIOS revisions 3 and 4)
- Eight ISA expansion slots (short type)
- Optional 8087 co-processor
- Optional second internal 360KB double-sided 5 1/4" floppy drive, if no internal hard disk
- Optional 'half height' 720KB double density 3 1/2" floppy drive
- Optional 10MB hard disk via 5161 expansion chassis
- Optional 10MB or 20MB Seagate ST-412 hard disk (in place of second floppy drive)
- Optional up to 2 external 360KB double-sided 5 1/4" floppy drive
- Optional Game port joystick ISA card (two analog joysticks with 2 buttons each)
- Optional Parallel port ISA card, Unidirectional (upgradable to bidirectional (as is on the ps/2) with some minor hacking; IBM had all the circuitry there but it wasn't hooked up properly)
- Optional Serial port ISA card
IBM PC Jr:
TODO: Which clock signals are available in a PC Jr?
- What clock is Y1? This eventually gets passed on to the CPU (ZM40?) and some other components by a 8284 (ZM8?).
- Is the clock attached to the Video Gate Array (ZM36?) exactly 14MHz?
IBM CGA/MDA:
Several different font roms were available, depending on what region the card was purchased in;
Currently known: (probably exist for all the standard codepages)
5788005: US (code page 437)
???????: Greek (code page 737) NOT DUMPED!
???????: Estonian/Lithuanian/Latvian (code page 775) NOT DUMPED!
???????: Icelandic (code page 861, characters 0x8B-0x8D, 0x95, 0x97-0x98, 0x9B, 0x9D, 0xA4-0xA7 differ from cp437) NOT DUMPED!

/* PC/3270 and AT/3270 have a set of two (optionally 3) 3270PGC programmable graphics controller cards on them which
have 2 extra roms, plus a number of custom chips and at least one MCU.
Information on these three boards plus the keyboard interface can be found at:
http://www.seasip.info/VintagePC/5271.html
*** The descriptions below are based on the cards from the AT/3270, which are slightly
different from the PC/3270 cards. Changes between the PC/3270 and AT/3270 video cards are
listed:
1. The card lip edge is changed on the APA and PS cards to allow them to be placed
in a 16-bit ISA slot.
2. The Main Display board is exactly the same PCB (hence cannot be placed in a 16-bit
ISA slot), but the socket to the left of the 8255 is now populated, and has a lot of
rework wires connected to various places on the PCB.
3. The APA board was completely redone, and no longer has an 8254 (though it does have an
empty socket) and has ?twice as much memory on it? (not sure about this). The APA
board also now connects to both main board connectors 1 and 3, instead of only
connector 1.
4. The PS board has been minorly redone to allow clearance for a 16-bit ISA connector,
but no other significant chip changes were made. The connector 3 still exists on the
board but is unpopulated. Connector 2 still connects to the Main display board as
before.
** The Main Display Board (with one 48-pin custom, two 40 pin customs at least one of which
is an MCU, four 2016BP-10 srams, an 8254 and an 8255 on it, a SCN2672 (PVTC), two crystals
(16.257MHz and 21.676MHz) plus two mask roms ) is stickered "61X6579 // 983623 // 6390 SU"
on the front.
* The pcb is trace-marked "6320987" on both the front and back.
* The card has a DE-9 connector on it for a monitor.
* The customs are marked:
"1503192 // TC15G008P-0009 // JAPAN 8549A" (40 pins, at U52)
"1503193 // TC15G008AP-0020 // JAPAN 8610A" (48 pins, at U29)
"(M)1503194 // XE KGA005 // 8616N XM // SC81156P" (40 pins, at U36, likely an MCU)
** The All Points Addressable (Frame buffer?) card (with 2 48-pin customs on it which are
probably gate arrays and not MCUs, an empty socket (28 pins, U46), an Intel Id2147H-3,
a bank of twelve 16k*4-bit inmos ims2620p-15 DRAMs (tms4416 equivalent), and an Intel
D2147K 4096*1 byte SRAM) is stickered
"6487836 // A24969 // 6400 SU" on the back.
* The pcb is trace-marked "EC 999040" on the back, and silkscreened "RC 2682819" on the front
* The customs are marked:
"6323259 // TC15G008AP-0028 // JAPAN 8606A" (48 pins, at U67)
"6323260 // TC15G022AP-0018 // JAPAN 8606A" (48 pins, at U45)
** The optional Programmable Symbol Card (with an AMD AM9128-10PC, and six tms4416-15NL DRAMS,
and a fleet of discrete logic chips, but no roms, pals, or proms) is stickered
"6347750 // A24866 // 6285 SU" on the front.
* The PCB is trace-marked "PROGAMMABLE SYMBOL P/N 6347751 // ASSY. NO. 6347750" on the front,
and trace-marked "|||CIM0286 ECA2466 // 94V-O" on the back.
